Visual studio 2015 使用testconn40.exe测试ibm数据服务器连接

您好，我在尝试测试与informix服务器的连接时出错。我所做的步骤：

1.安装IBM数据服务器客户端

2.安装IBM Data Server运行时客户端

3.之后，我使用cmd导航到数据服务器驱动程序包\bin\netf40 执行了这三行代码

gacutil /i IBM.Data.DB2.dll
gacutil /i IBM.Data.DB2.Entity.dll
gacutil /i IBM.Data.Informix.dll

4.Visual Studio内置IBM数据库外接程序（我有2015版）

我想做的是使用参考IBM.Data.DB2或IBM.Data.informix来替换连接到informix服务器的旧odbc方式

但是在做更多的事情之前，当测试我与testconn40.exe的连接时，我在步骤3中遇到了通信错误。下面是我在cmd中运行的代码

testconn40.exe -ids database=ibis2;server=192.168.1.2:9088;userid=informix;password=informix

这给了我这行代码

Unable to open socket to server:
ERROR [08001] [IBM] SQL30081N  A communication error has been detected. Communication protocol being used: "TCP/IP".  Communication API being used: "SOCKETS".  Location where the error was detected: "192.168.1.2".  Communication function detecting the error: "recv".  Protocol specific error code(s): "*", "*", "0".  SQLSTATE=08001
Some things to consider:
- is the port number correctly specified
  50000 is the default for LUW servers
    svcename dbm cfg parm for LUW servers
  446 is the only port for iSeries servers, default for zSeries
- for a LUW server, is the TCPIP listener started
  db2set DB2COMM=TCPIP, db2stop / db2start
- for an Informix server, ensure DRDA listener is started
  and you are using DRDA port vs the SQLI port
Test failed.

您的IDS服务器是否已启用DRDA连接？ 本机Informix CSDK使用SQLI协议进行通信，但IBM数据服务器驱动程序使用DRDA。 您在testconn40输出中看到的错误通常意味着您正在尝试连接到SQLI侦听器，而不是DRDA侦听器

基本上，您需要在onconfig文件中定义一个别名（dbserveralias），指向sqlhosts文件中以“drsoctcp”作为协议的条目

如果您已经完成了默认安装，它应该已经存在，因此只需使用该端口/服务而不是olsoctcp端口即可。

任何人都可以吗？我想我没有启用DRDA，请检查一下，谢谢：）
